如何在Unix中交换文件名? [英] How to swap filenames in Unix?

问题描述

有什么方法可以在不使用temp变量的情况下快速完成此操作?有内置功能吗?

Any way to do this quickly without using a temp variable? Is there a built in function?

谢谢大家的回答.看来我需要澄清我的问题，但在大多数情况下，你们都假设正确:有两个文件，而文件名却相反.

Thanks for the answers guys. Looks like I need to clarify my question but for the most part you guys assumed correctly: There are two files and the filenames names are reversed.

• 文件A的名称为B-name.file
• 文件B的名称为A-name.file

我想将文件A命名为A-name.file，将文件B命名为B-name.file.

I'd like for File A to be named A-name.file and File B to be named B-name.file.

我同意，这种情况不会经常发生，只是发生在我身上，我想快速解决.

I agree, the situation doesn't happen often but it just happened to me and I wanted a quick fix.

推荐答案

好的，愚蠢的问题，但是为什么不能简单地做一些事情(在shell脚本中):

ok, stupid question, but why can't you simply do something like (in a shell script):

mv $fileA $fileA.$$
mv $fileB $fileA
mv $fileA.$$ $fileB

是的，它当然使用一个临时文件，但是比其他答案更简洁.

and yes of course it uses a temporary file, but its more concise then the other answers.
